Package: grub-efi-amd64
Version: 1.99~rc1-13
Severity: important
I converted my system to boot with efi and found this to be quite hard
to try with this package (not the tiniest bit of documentation, leaves
the system without working bootmanager after install, etc).
So that is what I did to get this sort of working:
- made the efi system partition
- put an efi shell in it to be able to start the loader by hand
in case of emergency
- installed grub-efi-amd64
...and learned this package does absolutely nothing to make the
system bootable
- mounted the efi system partition at /boot/efi
- made the needed /boot/efi/efi subdir
- installed grub using
grub-install --boot-directory=/boot/efi/efi -bootloader-id=grub\
--no-floppy --recheck
which made the required /boot/efi/efi/grub directory at the
correct place with almost the correct content
- copied /usr/share/grub/unicode.pf2 into said directory because the
installer didn't do this and it seems to be needed for text with
efi_gop
and then ran update-grub which failed completely:
~# update-grub
Generating grub.cfg ...
cat: /boot/grub/video.lst: No such file or directory

~#
Besides generating a faulty configuration file it more
importantly is put at the completely wrong place.
update-grub puts it in the standard place for grub-pc
(/boot/grub/) whereas in case of uefi it just belongs into
/boot/efi/efi/grub/
Although from using grub-install before the correct path is in
principle known - it is not used and therefore each subsequent
usage of grub-update is destined to fail because the config file
is saved in the wrong place by default.
I finally got it working writing my own very basic grub.cfg and
placing this in the correct place
(/etc/boot/efi/efi/grub/grub.cfg)
side by side to the grub.efi bootloader.
After first starting it by hand from efi shell and then using
efibootmgr to make it the default bootloader the system is booting
well now.
But since update-grub doesn't work I have to adapt grub.cfg by hand
each time I install another kernel.
I hope this information is helpfull.

Marcus
